Predicate localTaintStep

Holds if taint propagates from nodeFrom to nodeTo in exactly one local (intra-procedural) step. This relation is only used for local taint flow (for example TaintTracking::localTaint(source, sink)) so it may contain special cases that should only apply to local taint flow.
